Title: Method and system for storing and searching chemical formula in database
Inventor: DOMINIKU RUNOO
IPC: G06F19/00
Filed: 1991-03-29
Abstract: PURPOSE: To retrieve a prescribed chemical formula out of a prepared list of Marcush formulas with high reliability and at a high speed. CONSTITUTION: Each of formulas includes a reference number and a spare selection number and is stored in a base file 14 in the form of a connection table. A list of all nodes including two right adjacent to each other is decided for every formula of the file 14 and a retrieved formula that is stored in the same form as the file formula. Then a full double environment fragment resulting from every node of the list is calculated. In regard to the 1st fragment of a retrieved Marcush formula, a 1st list of enable formula reference numbers is extracted out of a produced fragment file 18. Then the 2nd and subsequent lists are continuously extracted until a list resulting from the fragment of a formula having the optimum length is decided as necessary.  Then the spare selection number of the retrieved Marcush formula is compared with the spare selection number of the list formula resulting from the fragment. Thus the final list of candidates is obtained.

Title: Bar code reader
Inventor: SATO SHINICHI
IPC: G06K7/10
Filed: 1985-06-19
Abstract: PURPOSE:To read bar codes with the optimum time by identifying the bar code standard in a read mode and setting dynamically the reading time corresponding to the bar code standard. CONSTITUTION:When a sensor G1 detects the tip of an article, a timer 3 starts its actuation and a main control part 26 starts an optical unit control part 23. Reflected light sent from a bar code label is received by a photoelectric converting part 8. A PC recognizing part 19 extracts a parity pattern and informs it to a coefficient selection part 20 when a CPU/D standard is identified. The part 20 always sends a coefficient of a short reading time to a coefficient multiplying part 4 and switches the coefficient by the information. The timer 3 stops its actuation when a sensor G2 detects the tip of the article. Then the part 4 multiplies the count value (pass time) by the coefficient and sets them to a timer 5. The timer 5 starts its actuation when the sensor G2 detects the rear end of the article. When the timer 5 is subtracted down to zero by the time clock, the part 26 reads the demodulation data stored in a memory 22 by a demodulation part 9.

Title: Synchronizing contact device of electric shutter
Inventor: HOSONO TSUTOMU
IPC: G03B7/16
Filed: 1978-10-31
Abstract: PURPOSE: To surely synchronize even in the daytime synchro-flash photography and obtain correct exposure by providing a synchronizing switch which is turned ON by the signal of the ealier of shutter closing start time and delay time corresponding to object distance.  
     CONSTITUTION: In day-time synchro-flash photography, exposure time is shorter as the photo current of a photo detector 10 is large. Hence, a comparator 16 inverts early to de-energize a shutter-closing magnet 17. At the same time, a diode 23 is reverse-biased and therefore a capacitor 24 starts discharging, hence trasistors 27 then 36 go OFF. Because of this, firing current enters the gate of a thyristor 40 to turn this ON and emit light. In this way, strobe is let to emit light at the start of shutter closing and correct exposure may be obtained in the daytime synchro-flash photography of a short exposure time.
